Tubercular Synovitis of Knee-joint. 449 



surfaces is covered with fibrous tissue and granulations blanched 

 and altered by the spirit. 



It is difficult to say now whether the disease began in the 

 bone or the synovial membrane, probably the latter, from the 

 mischief seeming to have spread equally to both articular 

 surfaces. G- C. 109. 



Fresevted by Professor J. W. Turner. 



7. 58. Invasion of Articular Surfaces from Tubercular 

 Synovitis. — Upper end of a left tibia, partially destroyed by 

 the above. 



The greater part of the outer tuberosity is wanting, and 

 what remains of it has been deeply eroded. The rest of the 

 articular surface is rarefied and eroded. The tubercle and 

 adjacent portions of the bone have disappeared. There is a 

 slight periosteal crust round what remains of the tuberosities.

Synovitis. — Patella showing commencing rarefaction round 

 the edges of the articular surface. G. C. 1175. 



Presented by Professor Jajies Russell. 



7. 60. Invasion of Articular Surfaces from Tubercular
